In addition, the iTNC 530 also has two software option packets that 
can be enabled by you or your machine tool builder:
Please contact your machine tool builder to become familiar with the 
features of your machine.
Many machine manufacturers, as well as HEIDENHAIN, offer 
programming courses for the TNCs. We recommend these courses as 
an effective way of improving your programming skill and sharing 
information and ideas with other TNC users.
Location of use
The TNC complies with the limits for a Class A device in accordance 
with the specifications in EN 55 022, and is intended for use primarily 
in industrially-zoned areas.
Software option 1
